Pennation-
Angle
The pennation angle is the angle between the muscle fiber
direction and the muscle line of action. This angle changes when
the muscle contracts and elongates, and the model takes this
effect into account.
EPOTt The elastic potential energy stored in the tendon.
EPOTp
The elastic potential energy stored in the parallel-elastic element
of the muscle.
EPOTmt
The elastic potential energy stored in the entire muscle-tendon
unit. This can have some practical significance for investigation
of movement economy and sports activities in general.
Pt The rate of change of elastic potential energy in the tendon.
Pm The mechanical power of the contractile element.
